AI Technical Summary

Benefits of technology

The present invention relates to a display panel and device that has barrier walls to prevent substances from entering the panel through the film layers. The barrier walls are placed next to the transmitted subregion and a gap structure is formed between them. This gap structure prevents the substances from further entering the panel and allows for the continuous diffusion of water vapor. As a result, the display panel is protected from damage and has a longer lifespan.

Problems solved by technology

However, when setting the transmitted subregion, it is necessary to dig a hole in the display panel, which will cause sides of the organic light emitting diode device layer to be exposed to the air during cutting.
In existing packaging technology, packaging effect is unsatisfactory when the hole is packaged.
After the packaging, water and oxygen in the air easily penetrate into the screen, which causes the packaging of the display panel to fail and shortens service life of the display panel.

Embodiment Construction

[0063]Following descriptions of the embodiments are with reference to the attached drawings, which are used to illustrate specific embodiments that can be implemented by the present disclosure.

[0064]In the embodiment of the present disclosure, as shown in FIG. 1, it is a schematic view of a display panel in the prior art. The display panel includes a substrate 100, an array layer 101, a light emitting layer 102, and a encapsulation film layer 103. Meanwhile, the display panel further includes a transmitted subregion 104 and a display area 105. The display area 105 surrounds the transmitted subregion 104. In order to realize camera function, the transmitted subregion 104 is formed by digging an opening in the display panel, and a camera 103 is placed under the substrate 100 corresponding to the transmitted subregion 104. External light enters the camera through the transmitted subregion 104, thereby realizing the camera function.

Abstract

The present disclosure provides a display panel and a display device. The display panel includes a display area, a transmitted subregion, a substrate, an array layer, a first barrier wall, a second barrier wall, a light emitting layer, and a boss. The boss includes a plurality of step layers. The light emitting layer covers the boss and is discontinuous at the boss. The barrier walls and the boss prevent external substances from entering the panel through film layers, thereby effectively preventing continued diffusion of water vapor to protect the display panel.

Description

[0001]The present disclosure claims priority from a Chinese patent application filed with the Chinese Patent Office on Aug. 29, 2019 and with application number 201910806979.4, the title of which is “display panel and display device”, and entire contents of which are incorporated herein by reference.FIELD OF INVENTION[0002]The present disclosure relates to the field of display technologies, and particularly relates to a display panel and a display device.BACKGROUND OF INVENTION[0003]Compared with liquid crystal display devices, organic light emitting devices (OLEDs) have the advantages of self-luminous, fast response, light and thin, and have become emerging technologies in the display field.[0004]OLED display panels are widely used in field of electronic mobile terminals such as mobile phones. In order to increase a screen ratio of electronic products, a non-display area on the display panel is compressed smaller and smaller to achieve maximum display effect of the screen. In order...
